Hypersensitivity is the most common clinical problem which is encountered by most of dental patients undergoing a vital tooth preparation for a fixed crown prosthesis. The aim of this study is to evaluate the effect of silver diamine fluoride, potassium nitrate, and glutaraldehyde in reducing dentinal hypersensitivity following vital tooth preparation.
This study is a randomized control trial performed on 119 teeth of 68 patients who are in need of fixed prosthesis treatment.
After a thorough clinical examination, patients were allocated into any of the randomly assigned four groups (Control, silver diamine fluoride, potassium nitrate, and glutaraldehyde) and the level of hypersensitivity was measured by blasting air on the surface of tooth at five different intervals (before preparation, after preparation, after application of desensitizers, before cementation and after a follow up period of about 30 days) and is graded using Schiff 's cumulative hypersensitivity index.
Kruskal wallis test is used to compare the rate of sensitivity between the 4 groups. Friedman and Wilcoxon test is used to compare the rate of sensitivity at 5 different intervals.
All the desensitizers used in this study reduced the level of hypersensitivity. Among which, silver diamine fluoride was found to be more effective after application, before cementation, and after a follow up period of about 30 days followed by GLUMA and potassium nitrate.
The results of this study suggest that silver diamine fluoride was found to be more effective after application, before cementation of the definitive prosthesis and after a follow up period of 30 days.
过敏是大多数接受活髓牙预备以制作固定冠修复体的牙科患者最常遇到的临床问题。本研究旨在评估银胺氟化物、硝酸钾和戊二醛在活髓牙预备后降低牙本质敏感的效果。
这是一项在需要固定修复治疗的 68 名患者的 119 颗牙齿上进行的随机对照试验。
经过彻底的临床检查,将患者随机分配到四个组(对照组、银胺氟化物组、硝酸钾组和戊二醛组)之一,通过在牙齿表面喷射空气来测量过敏程度,在五个不同时间间隔(预备前、预备后、脱敏剂应用后、粘固前和大约 30 天后随访)进行测量,并使用希夫累积敏感指数进行分级。
使用 Kruskal-Wallis 检验比较四组之间的敏感率。使用 Friedman 和 Wilcoxon 检验比较五个不同时间间隔的敏感率。
本研究中使用的所有脱敏剂均降低了过敏水平。其中,银胺氟化物在应用后、粘固前和大约 30 天后随访时的效果更为显著,其次是 GLUMA 和硝酸钾。
本研究结果表明,银胺氟化物在应用后、粘固前和大约 30 天后随访时的效果更为显著。
